Greatham: questions and answers
Does your area include sites such as Longmoor Enterprise Park, near Greatham?
Yes. Our area takes in Greatham and its surroundings, with estates and business parks such as Longmoor Enterprise Park included. Photos and a short description are enough for a first look.
Is hospital work, at somewhere like Chase Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you guarantee expansion joint work?
A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Why do our movement joints keep failing?
It depends on how the sealant has let go: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Can staff carry on working while you are here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How we handle expansion joint sealing in Greatham
A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve water getting into the wall through a failed joint and leaks through car park deck joints onto the level below, across blockwork control joints, precast concrete panel joints and podiums and floor movement joints. Facilities teams, main contractors and managing agents in Greatham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller community and commercial buildings around Greatham have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Inspect exposed joints once the cold weather has passed
- Keep product details with the building records for the next reseal
- Avoid parking heavy plant or pallets on joint lines
- Include every elevation and deck joint in periodic inspections
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.
Slabs, ramps and loading bays in Greatham
Greatham lies roughly 45 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Greatham sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.
Hospital campuses such as Chase Hospital, 2.5 miles to the north-east of Greatham, grow in stages, leaving movement joints wherever new blocks meet old. In a school such as Greatham Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and our waste is bagged and taken away as we go. If others near Greatham need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site
- Flag any permit to work we will need
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Do you need expansion joint sealing in Greatham?
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again.
If one of these sounds familiar, it’s time for a closer look:
- Chipped joint edges on forklift routes
- Car park joints leaking onto vehicles below
- Previous reseals laid over old sealant
- Expansion joints filled with dirt and stones
Another example is Ham Barn Business Park, which lies south-west of Greatham, where floors and yards would be done in stages around the occupiers.

Leave it or put it right?
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme because damage continues. We can split the scope into urgent and planned. Halls, stores and units around places like Greatham may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
